Syria produced the most refugees last year - with 4.9m people fleeing the conflict in the country. One in every two people who lived there in 2011 is now listed at risk by the UN High Commission on Refugees.

The areas closest to the Syrian warzone have taken on the highest number of "at risk people".

UN General Secretary Ban Ki-Moon commented on the findings:

"We are facing the biggest refugee and displacement crisis of our time. Above all, this is not just a crisis of numbers; it is also a crisis of solidarity.”

Turkey tops the list with over 2.5m people, but Pakistan and Lebanon have taken in more than one million each.

The figure for Lebanon is particularly shocking, as the number represents almost a quarter of its population.

This means that much smaller and poorer countries are taking on a heavier burden than the UK, with regard to the worldwide refugee crisis.

Of the 123,000 refugees who lived in Britain in 2015, fewer than 5,000 were from Syria. But this number is double the year before, reflecting the start of David Cameron's pledge to resettle 20,000 Syrian refugees by 2020.

Commenting on the crisis, the UN High Commissioner on Refugees said:

“The willingness of nations to work together not just for refugees but for the collective human interest is what’s being tested, and it’s this spirit of unity that badly needs to prevail.”
